1) What are the distinctive properties of the following that create characteristic textures?
a) agar agar gel
b) carageenan gel
c) alginate gel
d) xanthan gum
e) pectin
ANSWER: a) Agar agar gel tend to be firm and brittle and, generally, develop turbidity due to the microfibrillar structure of the gel network.
b) Carrageenan gels vary from firm to soft with varying degrees of elasticity, depending on type.
c) Alginates form gels in the presence of calcium ions. These gels can be soft or firm, depending on alginate type and calcium content, and tend to be very elastic.
d) xanthan forms soft elastic gels in the presence of locust bean gum.
e) Pectins form soft, short-textured gels in high-sugar jams and confectionery jellies.
2) what are the important applications of the gelling agents?
